At a glance
sec-api.io facts come from its own pricing page, product index, MCP documentation and terms, read on 3 November 2026. It publishes no monthly call quota, and its Download API rate appears three different ways, so this page quotes neither. Narwhal API is owned and operated by Nusantara Ventures, LLC.

Price at your usage
sec-api.io states no monthly call allowance, so a price per 1,000 calls cannot be worked out. Narwhal Basic is $59 divided by 100,000 times 1,000, or $0.59 per 1,000 calls.
| Requests per month | Narwhal API | sec-api.io |
|---|---|---|
| 1,000 | Free: $0/month | The free key covers 100 calls in total, so this needs Personal at $49/month ($588 billed yearly). No allowance is stated |
| 10,000 | Basic: $59/month | Personal at $49/month, no allowance stated. Full-Text Search needs Business at $199/month |

Your companies are not all on EDGAR
sec-api.io says it covers all filings filed with the SEC, so a foreign issuer appears only through its SEC forms. Narwhal reads Japanese, Korean, Taiwanese, European and UK filers from their own regulators. Korea reaches about half of listed companies so far.
You want to ship on a free tier
The sec-api.io free key stops after 100 calls in total, and its terms limit it to personal, non-commercial use. Narwhal Free gives 5,000 requests every month and allows commercial apps. When the month runs out it returns a 429 and charges nothing.
Filings are one part of the data you buy
The same Narwhal key reads economics for 37 countries, FX for 144 currencies, calendars and stock listings from 42 exchanges. REST and MCP draw on one quota.
When they are the better pick
sec-api.io is the better pick for work on EDGAR itself. History runs from 1993 with over 20 million filings, and a real-time stream delivers new filings in under 300 milliseconds on every plan. Full-Text Search covers filings and exhibits published since 2001, on Business and Enterprise. It also offers filing downloads, a 10-K, 10-Q and 8-K section extractor, bulk datasets and form-level APIs such as 13F. Narwhal has no full-text search of filing text and starts US history in 2009.
